Exponent extrusion coated sealants have been engineered to offer a chemically clean and chemical resistant contact layer providing outstanding water vapor and oxygen barrier. Available in both peelable and weld seal versions, Exponent provides high-barrier clear film options where previous package choices were limited to aluminum foil laminations or glass. Exponent is available in several extrusion-coated and laminated configurations that incorporate PAXXUS’ ClearFoil® or Symphony™ aluminum foil product lines.

Exponent materials are ideal for pharmaceutical, including transdermal patch and single-dose delivery systems, diagnostic, cosmetic, e-cigarette, wine and spirit and other chemically-sensitive applications which require exceptional barrier and clarity. The Exponent Product Chart below provides guidance on Exponent high-barrier sealant options.
